CPC 18 Evacuated Tube Collector Available with Stainless Steel U-Tubes/Manifold

Big is beautiful and that is certainly the case with the CPC 18 evacuated tube panel. One of the best performing solar panel systems on the market offering higher yield per square meter of roof covered than any other panel on the market. The stainless steel U tubes and manifold also help to increase the output of the panel over the standard copper based version of this panel.

The CPC stainless steel evacuated tube collector is a specialist system developed especially for solar water heating and for solar backup heating. The low pressure loss allows several modules to be connected in series. Aperture area measurements of 3.0 sq meters allows for accurate adjustment to water and/or space heating requirements.  Careful attention has also been made to details that are important to mounting the system, where maximum movement of the rails to the anchor point means that even the least accurate installer can get the rails into a straight line.

Extra Cooling Vessel

We recommend the use of an Extra Cooling Vessel when installing any evacuated tube collectors, if the length of pipe between the solar panels and the expansion vessel is less than 10 meters then it is essential that an Extra Cooling Vessel is fitted.

If the collectors begin to stagnate and fluid starts to boil, then it will force it's way back down the return pipe in the form of steam. If the steam makes it back as far as the expansion vessel then it will quickley destroy the diaphram in the expansion vessel. Fitting a 5L Extra Cooling Vessel adds an extra 5L of fluid that needs to turn to steam before it gets to the expansion vessel.
